4wd went out

[Bosshawg600]

I went to pull someone out of the snow and 4wd worked fine then tried putting it in later that day and no 4wd I can see the front drive shaft spinning but thats it. Help would be greatly appreciated.

Check all the vacum lines and make sure they are all still attached, I have had a problem with them getting knocked off.

Is the front shaft spinning under power?? If it is, and the wheels are not turning you have one of two things, no vac supply to the center axle disconnect or a faulty actuator in the CAD.

Or even the possibility that the front CAD collar shattered.
